It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) advised Hazrat Salman Farsi (may Allah be pleased with him), who was famous by the name Salman al-Khair, saying that the Prophet of Allah wishes to present you with a few words through which you can ask from the Most Merciful, express your desire towards Him, and call upon Him day and night with these words. Thus, you should say: O Allah, I request from You the correctness of faith, good character along with faith, and such success in which there is prosperity in both worlds. And I seek from You Your mercy, well-being, forgiveness, and pleasure.
